Abstract
A Fin Bulk Acoustic Resonator (FinBAR) includes a fin integrally fabricated on a substrate of a glass or a semiconductor, an inner electrode deposited on the fin, a piezoelectric layer disposed on the inner electrode, an outer electrode deposited on the piezoelectric layer, a first electrode and a second electrode formed on the top surface of the substrate and connected to the inner and outer electrodes respectfully. The fin is characterized with a larger height than its width. A FinBAR array including a number of the FinBARs with different fin widths sequentially located on one chip is capable of continuously filtering frequencies in UHF and SHF bands.
